PART A: i) Male: Female: The mean value of life satisfaction for male is about 7.7459 while for female is 7.7101‚ which proves there is no significant different life satisfaction between male and female‚ thus gender does not affect life satisfaction a lot. But when it comes to sample variance‚ for male is 2.5684 while for female is 3.0081. From this pair of figures it is obvious that the life satisfaction for female is more flexible than male. Man’s life satisfactions are easy to be affected

TASK: My aim is to determine the relationship between the number of calories someone consumes in a day and the number of hours someone sleeps at night. Food is consumed as fuel; it contains calories that give you energy‚ and those calories burn off as you use them. The definition of a calorie is the amount of heat required at a pressure of one atmosphere to raise the temperature of one gram of water one degree Celsius. I want to see if the amount of “energy” someone takes in affects how they sleep

The usage of graphs are essential in the illustration and comprehension of statistical output. They type of graphs used depends on the author and the view they are trying to portrait. Graphs can be used to prove or disprove a theory based on its presentation. The Following graph is used as a visually depiction of a sample of grade school childern of whom an IQ exam was performed.

4.4 Quadrature phase shift keying (QPSK) Quadrature phase shift keying (QPSK) has twice the bandwidth efficiency of BPSK since two bits are transmitted in a single modulation symbol. In the phase of the carrier takes on one of four equally spaced values‚ such as 0‚ π/2‚π and 3π/2‚ where each value of phase corresponds to a unique pair of message bits. The Quadrature phase shift keying (QPSK) signal for this set of symbol states may be defined as s_QPSK (t) =√(〖2E〗_s/T_s ) cos[〖2πf〗_c t +(i-1)π/2]

The results connected with the aim of the study are as follows: 1. The most suitable light shelf size/position is determined on 6 latitudes for 3 different office heights. 2. The correlation between light shelf size/position and latitude is created from arrangement of light shelves according to latitudes for different office heights. 3. CUN-OKAY light shelf curves are obtained by joining interior and exterior end points of suitable light shelves separately according to latitudes for 3 different office

Running head: SOCIAL FACILTATION OF COMPLEX TASKS Social Facilitation of Complex Tasks: A Comparison of Zajonc ’s Drive Theory and Cottrell ’s Evaluation-Apprehension Theory Abstract Zajonc (1965) describes Drive Theory as the increase in levels of arousal in the presence of others which enhances the frequency of dominant behaviours. The aim of this experiment was to challenge Zajonc ’s theory. This study encompassed ten University students and ten teachers and examined the effect of an Attentive
